Do you think the Picard Series will revitalize the Romulans? Of all the major Star Trek civilizations, the Romulans seem like the least explored of them. All the other civilizations the Klingons, the Bajorans, the Cardassians, the Ferengi, the Dominion, and heck even the Borg have more major characters in the franchise then the Romulans. The Romulans were interesting in their first appearance, but the Klingons took the role of the honorable enemies and by the TNG era, they just became generic bad guys who would do something underhanded, got caught and creep away. I think one problem is the Romulans are kinda just Space Romans, with a Proconsul, Praetor and Senate and an alien civilization that is just a copy of an Earth civilization is kinda dull and lazy. To me, the more interesting thing about the Romulans is they shared heritage with the Vulcans. They were the most reoccurring villains in TNG, but did not get much in the way of major characters or development on the screen (I do not think Sela or Tomalak is on the same level as characters like Garak or Dukat, for example). Star Trek Nemesis was supposed to be a Romulan centered film, but the spotlight ended up going to the Remans and a Picard clone in that film. However, the destruction of Romulus finally gives the Romulans a new take, that could revitalize this civilization that has become stale in terms of storytelling. A major civilization that has completely lost its homeworld to a natural disaster is somewhat unique in Star Trek and the Romulans being more nomadic could be interesting. We see a Romulan character as one of Picard's crew and with the Romulans seemingly experimenting with Borg tech and having more reason to be bold due to their desperate circumstances, maybe we could see a truly menacing main Romulan villain, along with some sympathetic Romulans. Really I think most of the hanging plot threads from the TNG era Star Trek involve the Romulans.
